Ricoh MP 6002 error SC220: Laser sync failure
The Ricoh MP 6002 error SC220 indicates a critical failure in laser beam synchronization. This happens when the polygon motor fails to reach the speed needed for projection or the synchronization sensor fails to receive the trigger signal. It is an internal fault requiring an inspection of the copier's imaging system.
Common causes
- 1Polygon motor failure: The motor distributing the laser fails to reach sync speed.
- 2Sensor dirt: Toner particles blocking the laser ray start-up sensor.
- 3Controller board problem: Logic board fails to receive laser response.
- 4Mechanical misalignment: External vibrations that have adjusted the internal laser beam.
Solutions
Diagnóstico rápido
If you receive the SC220 error on your Ricoh MP 6002, there is likely a fault in the laser motor or the synchronization signal is interrupted. Listen for a high-pitched whirring sound when attempting to start the system.Solución paso a paso
- Power reset: Turn off the equipment completely, wait 30 seconds, and turn it back on.
- Check internal cables: Verify that the laser unit connector is not loose due to vibrations.
- Check environment: Ensure no direct light is shining on the glass during the startup process.
- Test print: Send an internal print test to see if the error persists after resetting.
Prevención y mantenimiento
Avoid moving the copier after installation to prevent mirror misalignment. Use original toner, as generic toners often shed more dust that can clog the laser unit. Annual expert maintenance is recommended.Cuándo llamar a un técnico
The SC220 error almost always requires replacement of the laser unit or its controller board. Do not attempt to open the laser unit's seal yourself.Ficha técnica del equipo
